Function
C1100 = 1
•
For|counter|≥ | FCNT1-CMP-VAL | (comparison value):
– For 1 ms FCNT1-EQUAL = HIGH
– Resets the counter to its start value (FCNT1-LD-VAL)
Note!
If the signal is to be set for a longer time, e.g. when the output is requested by a PLC, you can extend
the signal with the TRANS function block.
C1100 = 2
•
For | counter | = | FCNT1-CMP-VAL | (comparison value):
– The counter stops
•
FCNT1-LOAD = HIGH resets the counter to the start value (FCNT1-LD-VAL)
